Application filed May 21, 1919, Serial No. 298,638. Renewed February 20, 1923. Serial No. 580,329.

T0 all Lo/tom t may concern Be it known that l, BYRON B. GoLnsMirH, a citizen ot the United States, residing at New York, in the county ot New York and 5 State ot llew York, have invented certain new and useful Improvements in lnk Cartridges; and l do hereby declare theV following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a new and improved means for producing ink conveniently, rapidly and efficiently. Many l5 di'li'erent devices have been tried for producing ink by the simple addition of water to the ink-producing materials. These have either been contained in special receptacles, or have been in the form of tablets to be dissolved in water. @t these methods the only one which has survived is the ink tablet, as the 'former did not produce a suitable ink.

The disadvantage of using the ink tablet is readily understood when one considers that r to make ink from ink tablets it is necessary to take a measured amount of water for each tablet and place both in a suitable receptacle and agitate until there has been complete solution. ln other words, it almost amounts to as much trouble in a small way as the manufacture of liquid ink does on a large scale. The consumer becomes the Aink manufacturer. For this reason ink tablets are used very little. The desire to iind substitutes for the liquid ink of commerce, arises from three disadvantages it has: Firstly, it is bulky and takes up much space in the factory, on the railroads, and in the dealers stock. Secondly, it is shipped in glass and there is considerable expense in packing sately, notwithstanding which breakages cannot be avoided. Thirdly, it cannot be shipped in winter asit freezes,

ruining the ink or the bottles or both. B v

the use of my invention it is possible for any unskilled person to produce ink oi the liuest qualit)Y almost instantaneously.

The basic principle ot this invention rcsides in supplying narrow passages for the water wholly or partly lined with ink pruducing material, which passages are artiicially constructed with such a delinite relative proportion between their diameter and length that, as the water passes through them, it necessarily has time to take up the required amount of material to produce a satisfactory ink. The use of a single channel would be within this principle of oonstruction, in which case if the channel is wide enough to have'the liquid flow rapidly it would have to be long enough to allow the liquid to dissolve sutiicient material, or if the channel is narrow the liquid would iiow more slowly and the channel need not be so long. It is a little simpler, however, to employ a number of passages.

The general principle underlying this invention is capable of being carried out in a variety of ways, .some of which are set forth in certain copending applications for Letters Patent. rihere is claimed herein that general form or embodiment wherein ink producing material is wound or folded upon itself with percolating channels between the layers. These can be arranged so that the channels run in any direction, and these channels may take a variety of forms. The

material may be in a single mass or be in the form of a coating upon a suitable backing.V In either ease it may be combined with a similarly wound or folded sheet of neutral material.

A few ot many possible specific embodin'ients ot the invention herein vclaimed are illustrated in the accompanying drawings, wherein Figures l and 2 are plan views ot' simple spiral arrangements, Figure 8 is a similar view of a return-curve arrangement, Figures 4l and 5 are views in elevation of two iorms of ribbed sheets shown unwound, Figure 6 is a perspective view of a composite ribbed sheet as wound for use, Figure 7 is a partial crosssectional view of the. form shown in Figure 6, Figure 8 is a cross section of a ribbed sheet having a core oi fabric and suitable Jfor-use in the manner shown in Figure 6, and Figure 9 is a vertical sectional view oli a. moeitication employing an inl:-produeingv body wound in an extended spiral. .lt is to be understood that the passages or channels, as formed in the devices actually manufactured, will not be exactly as shown in the drawings. As already stated, the actual diameters and lengths of the passages will be experimentally determined for each particular type ot device and character of ink.

In the form shown in Figure l the inkproducing body is a simple sheet l0 (viewed edgewise in the figure) and arranged spi-- rally within a casing 11, which may or may not be faced within with ink-producing material. In this form a large opening is left at the center, which will serve as a dipping space for the pen. When water is made to enter the peripheral space 13, it will follow the farrows through the spiral passage 111, and will enter the dipping varranged in folds or return curves. VThey maybe supported or fastened in any convenient manner, the drawing. being virtually in the nature of a diagram.

Instead of forming percolating passages extending over the entire area ofthe sheet or sheets,conined passages may be formed.

This'is preferably accomplished by using ink-producing sheets having ridges or ribs. Thesemay extend longitudinally, as shown at 18 in Figure a, or transversely as 11,9 in Figure 5.v In the former case the channels will be spiral and extend inward and hori` zontally; being best fitted for the arrangement shown in Figure 1. In the latter case the percolating passages will extend longitudinally7 and will be used as described above for Figure 2. Y l

VOne arrangement aflfordingspiral confinedy passages is shown in perspective in Figures 6 and 7. Here the ink-producing material 20 is supported upon a spiral backing, 21, which may or may not contain ink-producing material, and is formed with ridges or ribs 22, limiting the percolating passages. As shown,l these ribs are given a definite pitch, so, as to form double spirals. This lengthens theresulting percolating passages.

Aas shown in. Figure 8, the ink-producing material may be made by coating or thickly impregnating an inner sheet of fabric `23), and where the ribs 24; are used, their formain place in any convenient manner, as byV the casing 28. In this case the percolating space will also talre the form of an extended spiral. In the modification just decribed the ink-producing body may be conveniently produced by iinpregnating a cord ofl cotton or other fabric with ink-producing material. A Y

The term wound7 as used in the claims hereof is intended to cover any of the ldispositions of the material herein shown or qnivalents thereof; and in claiming a body or a sheet it is to be understood that I intend to cover devices employing `either one or more bodies or sheets, wound for the purpose described.

It is clear from the few examples above set forth that the prese-nt invention is capable of many modifications,V and that its scope is not to be limite-d to thendetailsherein shown and described. Y

lWhat is clannied is-f 1. An: ink cartridge comprising a body wound so as to form-a sinuous percolating passage between contiguous layers, and` inl;- producing material upon a wall of the passage so produced. Y I Y 2. Means set forth generally in claim. 1 hereof wherein the sinuous passage assumes a. spiral form. I Y

3l Means set forth generally in claim 1 hereof wherein the body takesthe form of a sheet provided wi th Spacing ribs and spir ally disposed so as to leave a percolating Space between saidribs.

In testimony whereof I afx my signature.
